To all] 1071mm it may concern [Be it known that 1', Fnennnron T. Venom, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State oi Indiana, have invented certain new andusetul Improvements in Antiskid Attachments, oi which the following isla specification. l

The invention relates to antiskid attachments for automobile wheels, and has for its ob ect to provide an elongated segmentally shaped plate segmentally shaped in longitudinal. and transverse cross section and adapted to engage and be disposed on the tread oi? the tire and held thereon by means of chains. Also to provide the antiskid device with transversely disposed plates, in eyes at. the ends of which chains are secured,

which chains pass over thectelly of the wheel around the adjacent spoke and thence to a hookcarried by the end of the other transversely disposed plate, which hO0k 1SJd1S- posed. on the same side of the device as the eye from which the chain starts. 25.

Also to provnleachain connected to one of the plates at the opposite sides of the device, which chain passes around thespoke and thence to a hook carried by the other plate and located on the same side of the device.

A further object is to provide chains of sufficient length to allow the device to be applied to various sizes of tires and wheels.

A further object is to provide an antiskid device comprising a tire tread engaging plate segmentally shaped in transverse and longitudinal cross section, said plate having secured to its outer side transversely disposed segmentally shaped plates spaced from each other and provided with chain connecting means at their ends for holding the device in engagement with the tire. Also to provide a longitudinally disposed member bent to form transversely disposed ground. engaging ribs disposed above the transversely disposed plates, and also bent to conform to the transverse contour of the plates.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set :I'orth, shown in the drawings, and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from thespirit of the invention.

In the drawin Figure 1 is a s de elevation of a portion of taken on line 3-3 of Figure 1.

Referring to the drawing, the numeral 1 designates the telly of a conventional form of automobile wheel, and 2 the tire receivchannel carried thereby in the flanges 3 of which a conventional form of pneumatic tire 4 is held. The telly 1 is provided with conventional spokes 5, one of which is shown for illustrative purposes. The antiskid device comprises the tire engaginguplate 6, which plate is segmentally shaped in longitudinal and transverse cross section and is adapted to be placed on the trend 7 of the tire and held in engagement with said tread, in such a manner that the wheel will be held against skidding and against spinning, or slipping as the vehicle advances. Secured to the outer face of the plate 6 "by means of rivets 8 are transversely disposed segmentally shaped plates 9, which plates haveone of their ends provided with eyes 10 for the reception of the ends 11 of the securing chains 12, which chains pass over the telly 1, thence around the spoke 5 and extend outwardly over the side of the telly adjacent the other ortion of the particular chain and have tiieir free ends connected to the hooks 13 of the plates 9. It will be seen that by providing chains passing around the spoke 5 as set forth that the device will be securely held on the tread 7 of the tire and will be prevented from transverse movement as well as circumferential movement in relation to the tire. The chains 12 are preferably of suflicient length to allow the device to be applied to various sizes of automobile wheels and tires. Secured to the plate 6 by means of rivets 14 is a longitudinally disposed member 15, the ends of which member are bent at right angles at 16 to form portions 17, which overlie the transversely disposed plates 9. Portions 17 are in turn bent at right angles to form the outwardly extending ground engaging members 18, which members bite into the ground and prevent spinning of the wheels as well as preventing skidding of the wheels.

From the above it will be seen that an antiskidding device is provided for automotires.

bile wheels, which device is simple in construction, and one wherein the ribs lS are formed by bending the longitudinally dis posed strip 15 to form the ribs, which ribs are disposed'above the plates 9 and carried by members which arch the.plates9,thereby protecting the plates 9 and their securing means b from vear, and at the same time holding the plates 9 against pivotal movement on the rivets S.

I The invention having been-set forth what claimed as new and useful isz l. An antiskid device for, wheels having spokes, said device comprising a plate segmentally shapedindongi tudinal and transverse cross section and adapted to engage theYtread of a tire, transversely disposed plates secured to the segmentally shaped plate, chains connected to the ends of tl e transversely disposed plates at diametrically opposite sides, said chains passing around the adjacent spoke of thewheel, the free ends of said chain being detachably secured to the ends of the plates at diametricallyopposite sides, said chains being of sufiicient length to allow the device to be applied to various sizes of wheels and 2. An .antiskid wheels, said device comprising an elongated plate segmentally shaped in longitudinal and transverse cross section, transversely disposed members secured to the elongated plate'adjacent its ends, a longitudinally disposed reinforcing plate secured to the outer face of "the segmentally shaped elongated plate, said reinforcing plate being formed device for automobile from a single piece of material and bent to arch the transversely disposed members, said longitudinally disposed reinforcing plate being bent upon itself to form ground engaging elements disposed over the transversely disposed members, and means connected to the ends of the trausvcr.- sel dis- .posed members forsecurely holding the device as a whole in position on the tire.

3. An antislnd deuce comprising an clongated tire engaging plate, transversely disp posed members secured to said plate and automobile bers secured to said plate, means carried by the ends of said transversely disposed members for the reception of securing means, a reinforcing plate secured to the elongated tire. engaging plate and arching the transversely disposed members, said reinforcing plate being bent upon itself centrally of the arched portions thereof and forming outwardly extending ground engaging memhere.

In. testimony whereof I aflix my signature.
